Action potential is a phenomenon that occurs when the membrane potential of a living cell first increases and then decreases. This is a characteristic trait for a range of living cells, including neurons, muscle cells and endocrinological cells. Certain plant cells also produce them. Neurons play a vital role in cell-to-cell communication. In the beta cells of the pancreas, the action potential is associated with releases of insulin. Plasma membranes comprise a particular kind in voltage-gated, ion-channels that are used for producing action potential. They remain closed when the membrane potential is within the potential at rest of the cell . However, if the membrane potential increases then the channels are activated. When the channels open they allow for an inward flow sodium ions, which boosts its membrane potential. The rapid flow of sodium ions alters the membrane's polarity and , in the process, are inactive. The potassium channels after that are activated and it is a flow of the potassium ions . This causes the membrane is returned back to its normal state. A transient positive shift known as refractory interval prevents further moving of the action-potential. In animal cells generally , two types of potentials are well-known, such as one because of voltage-gated sodium channels, and another that can be produced by calcium channels that are voltage-gated.

Nearly all cells maintain some degree of voltage variation between their interior and exterior environment. The voltage of the cell is measured in milli volts (mV). The voltage of a typical animal cell is around -70 mV. In the majority of cells few voltage fluctuations are believed to be present, however in some cells this is a regular characteristic. Cells can show periodic up and down oscillations as the voltage increases and declines. The duration of these potentials can be varied over a broad spectrum. In brain cells the up and down cycle of the action potential is completed in less than a thousandth of a second, whereas in other types of cells , intervals may be prolonged to several seconds. The electrical ability of an animal cell is dependent upon the membrane structure. Cell membranes consist of an outer layer of lipids as well as proteins. The lipid layer acts as an insulator.

Animal cells are all electrically polarized , as they sustain a voltage variation called membrane potential. For neuronal cells, axons and cell bodies have different electrical characteristics. The most excitable component of neuron is called the axon hillock, but the axon and the cell body can also be excited. The axon hillock's maximum resting power is -70 mV and the threshold potential is 55 mgV. Synaptic inputs into the neuron cause depolarization, causing the membrane potential to rise or fall. A potential for action is created when enough depolarization is accumulated and the membrane current reaches an upper limit.

Action potential is the result by the action of voltage-gated channels that reside in the plasma membrane of a cell. A voltage-gated Ion Channel is in fact a collection made of proteins. They remain in plasma membranes and generates an action potential since it could give rise to the positive feedback loop. Membrane current is responsible control of the activity of Ion channels. Action potential is generated during the time that the feedback cycle proceeds with full intensity. Its duration and amplitude are dependent on the bio-physical properties of the ion channel voltage-gated. Many kinds of ionchannels are identified that generate positive feedback and lead to the generation of these potentials. Voltage-gated sodium channels play a role in the creation of fast potentials that are similar to nerve impulses. Slower ones like those produced by muscles cells are controlled by calcium ion channels.The most studied voltage-gated Ion channels are the sodium ion channels participating in the speedier nerve impulse conduction.
